Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to a high-efficiency finned heat exchanger. Background Technology

[0002] Finned heat exchangers are devices that achieve efficient heat exchange by expanding the heat transfer area. Their core structure consists of a base tube and additional fins. They are widely used in energy, industry, transportation and other fields. Hot fluid flows through the inner wall of the base tube and conducts heat to the outer wall of the tube. The fins, as an extended surface, transfer heat from the tube wall to the surrounding fluid. Cold fluid flows through the gaps between the fins, absorbs heat and its temperature rises. The convective heat transfer between the fin surface and the fluid, as well as the heat conduction inside the fins, work together to complete the heat exchange.

[0003] During operation, dust and impurities in the air tend to accumulate and adhere to the gaps between the fins of a finned heat exchanger, requiring regular cleaning. Cleaning not only necessitates pausing the heat exchanger and interrupting the continuous operation of the heat exchange system, but also the narrow gaps between the fins make it difficult to clean the interior of the gaps. To address these issues, we propose a high-efficiency finned heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency finned heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency finned heat exchanger includes a connecting frame. A heat-conducting copper tube is fixedly connected to the outer surface of the connecting frame. Multiple heat dissipation fins are fixedly connected to the outer surface of the heat-conducting copper tube. A connecting shell is fixedly connected to the upper surface of the connecting frame. A bearing is embedded in the inner top wall of the connecting shell. A threaded rod is fixedly connected to the inner ring of the bearing. A motor is fixedly connected to the upper surface of the connecting shell. The output end of the motor is fixedly connected to the upper surface of the threaded rod. A lifting frame is threadedly connected to the outer surface of the threaded rod. Two lifting shells are fixedly connected to the bottom surface of the lifting frame. Multiple soft bristles are fixedly connected to the outer surface of each of the two lifting shells. Multiple adsorption holes are opened on the outer surface of each lifting shell. A negative pressure shell is fixedly connected to the front of the connecting shell. Two negative pressure fans are fixedly connected to the inner side wall of the negative pressure shell. A filter screen is fixedly connected to the inner side wall of the negative pressure shell. A connecting pipe is fixedly connected to the upper surface of each of the two lifting shells. Each connecting pipe is connected to the negative pressure shell.

[0007] In a further embodiment, a controller is fixedly connected to the right side of the connecting shell.

[0008] In a further embodiment, two light rods are fixedly connected to the inner top wall of the connecting shell, and each light rod is slidably connected to the lifting frame.

[0009] In a further embodiment, two positioning magnetic blocks are fixedly connected to the right side of the lifting frame, and a Hall sensor is fixedly connected to the inner side wall of the connecting shell.

[0010] In a further embodiment, a sealing door is rotatably connected to the front of the negative pressure shell via a hinge, and two flanges are fixedly connected to the outer surface of the heat-conducting copper pipe.

[0011] In a further embodiment, a base plate is fixedly connected to the bottom surface of the connecting frame, and rubber pads are fixedly connected to the bottom surfaces of both lifting shells.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a motor to drive a threaded rod to rotate, which in turn moves the lifting shell and soft brush bristles up and down along the heat dissipation fins. The soft brush bristles can penetrate deep into the gaps between the fins to sweep away attached impurities. A negative pressure fan generates negative pressure, which is conducted through a connecting pipe to the lifting shell and sucked up the swept dust through the suction holes. The swept dust is immediately collected in the negative pressure shell. This double cleaning prevents dust residue from accumulating and eliminates the need for manual disassembly or machine shutdown, effectively avoiding interference with the continuity of heat exchange during cleaning and ensuring the stable and efficient operation of the heat exchanger.

A heat-conducting copper tube 2 is fixedly connected to the outer surface of the connecting frame 1. Multiple heat dissipation fins 3 are fixedly connected to the outer surface of the heat-conducting copper tube 2. A connecting shell 4 is fixedly connected to the upper surface of the connecting frame 1. A bearing 5 is embedded in the inner top wall of the connecting shell 4. A threaded rod 6 is fixedly connected to the inner ring of the bearing 5. A motor 7 is fixedly connected to the upper surface of the connecting shell 4. The output end of the motor 7 is fixedly connected to the upper surface of the threaded rod 6. A lifting frame 8 is threadedly connected to the outer surface of the threaded rod 6. Two lifting shells 9 are fixedly connected to the bottom surface of the lifting frame 8. Multiple soft bristles 10 are fixedly connected to the outer surface of each lifting shell 9. Multiple adsorption bristles are formed on the outer surface of each lifting shell 9. Hole 11, a negative pressure shell 12 is fixedly connected to the front of the connecting shell 4. Two negative pressure fans 13 are fixedly connected to the inner wall of the negative pressure shell 12. A filter screen 14 is fixedly connected to the inner wall of the negative pressure shell 12. Connecting pipes 15 are fixedly connected to the upper surfaces of the two lifting shells 9. Each connecting pipe 15 is connected to the negative pressure shell 12. The connecting pipe 15 is a reinforced rubber tube that can deform with the movement of the lifting shell 9 and has pressure resistance. By rotating the threaded rod 6, the soft brush bristles 10 can be driven to move up and down along the heat dissipation fins 3. With the help of the negative pressure fans 13, the dust swept off the parts is sucked into the negative pressure shell 12 through the adsorption hole 11 and the connecting pipe 15, avoiding the accumulation of dust residue and enabling the heat dissipation fins 3 to continuously and efficiently dissipate heat.

[0023] A controller 23 is fixedly connected to the right side of the connecting shell 4. Two light rods 16 are fixedly connected to the inner top wall of the connecting shell 4. Each light rod 16 is slidably connected to the lifting frame 8. Two positioning magnetic blocks 17 are fixedly connected to the right side of the lifting frame 8. A Hall sensor 18 is fixedly connected to the inner side wall of the connecting shell 4. By setting the light rods 16, the movement of the lifting frame 8 is guided. After the Hall sensor 18 detects the positioning magnetic block 17, it sends a signal to the controller 23. The controller 23 controls the motor 7 to reverse, so that the soft brush bristles 10 continuously clean up and down.

[0024] The front of the negative pressure shell 12 is connected to a sealing door 19 via a hinge. Two flanges 20 are fixedly connected to the outer surface of the heat-conducting copper pipe 2. A base plate 21 is fixedly connected to the bottom surface of the connecting frame 1. Rubber gaskets 22 are fixedly connected to the bottom surfaces of the two lifting shells 9. By setting the flanges 20, and with the sealing gaskets and bolts and other metal parts, the liquid pipe can be connected to the heat-conducting copper pipe 2. By setting the rubber gaskets 22, when the lifting frame 8 is in a high standby state, the rubber gaskets 22 can prevent dust from entering the connecting shell 4. A sealing ring is fixedly connected to the outer surface of the sealing door 19.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the pipe is connected to the heat-conducting copper pipe 2 via flange 20, allowing heat to be conducted to the outer surface through the pipe wall of the heat-conducting copper pipe 2. The heat dissipation fins 3 expand the heat exchange area, and the external fan blows heat onto the heat dissipation fins 3 for heat dissipation. The motor 7 drives the threaded rod 6 to rotate, and with the guidance of the smooth rod 16, the threaded rod 6 drives the lifting frame 8 and the lifting shell 9 to move up and down. The soft brush bristles 10 adhere to the heat dissipation fins 3 to clean the dust. At the same time, the rotation of the negative pressure fan 13 generates negative pressure, which is conducted to the lifting shell 9 through the connecting pipe 15, sucking in the dust and transporting it into the negative pressure shell 12. The sealing door 19 can be opened to clean the filter screen 14. The positioning magnetic block 17 and the Hall sensor 18 work together to control the motor 7 to reverse, so that the lifting frame 8 can reciprocate to cover all the fin cleaning areas, ensuring continuous and efficient heat exchange of the equipment.
